Help required please - in-house Exchange to Hosted - routing

Hi,

I am posting here for some advice please.

We have just migrated a customer's in-house SBS Exchange 2007 to a cloud-based Exchange solution (OneNet) but have had to keep one email domain in-house for now (don't ask).

How can I configure their Exchange server to send email to the newly created external OneNet mailboxes from that one in-house email domain? At the moment it appears to just want to route internally (to the old, in-house mailboxes) as it has always done in the past.

I'm thinking something via Exchange Console -> Hub Transport -> Organisation -> Send Connectors - SMTP?

Thanks,
Peter

If the in-house Exchange server no longer has references to the domains that have been moved to the external server, then Exchange should route all email (including those domains you've migrated) externally, and through that to the new cloud provider. If that's not happening then I'd expect your issue is that Exchange still thinks that it is responsible for the domain.

First thing to check, go into Organization Configuration > Hub Transport > Accepted Domains, and check that those migrated domains aren't still listed as Authoritative (or Internal Relay). If they are then depending on your setup you can either simply remove them from here, or if there are still any references to the domain locally (that you need to keep) then change them to External Relay, which will then forward any mail destined for an address not held locally out via the internet.

If your server is unable to lookup the migrated domains, and resolve them to the new hosting in the same way it would do for any other domain, then you'd want to add a Send Connector. Most likely causes would be that you've had to keep a reference to them in Accepted Domains, or the local DNS still has the domains listed locally with records pointing elsewhere. If that's the case then you could add a send connector for them within Hub Transport, and from there route all mail destined for one of those domains through the relevant smart host, eg the inbound server address of your cloud based Exchange server.
